Two types of direct l-type resonance transitions induced by the (.DELTA.k = +/-2, .DELTA.l = +/-2) interaction could be observed: 262 transitions following the .DELTA.J = 0, .DELTA.k = .DELTA.l = 2 selection rule covering values of J = 17-64 and G = midk - lmid from 2 to 15, and 75 transitions following the .DELTA.J = 0, .DELTA.k = .DELTA.l = 4 selection rule covering values of J = 44-70 and G up to 3. The strong (2, 2) resonance furthermore allowed the observation of A1-A2 splittings of the k = l = +-2 states from J = 63-70. The transitions with G = 3 showed splittings due to the (4, -2) and (0, 6) interactions. The corresponding energy level systems and part of the Hamiltonian matrix are discussed. Workplace J.
